567476b89a cmake: Explicit dependency for mraa and interfaces
A handful of modules do not require mraa.  Captured this in
    src/CMakeLists.txt - only add mraa dependency for targets which
    use:

        upm_module_init(mraa ... )
            or
        upm_mixed_module_init(... REQUIRES mraa)

    All sensors which use UPM interfaces (src/interfaces) now
    explicitly add the interfaces target:

        upm_module_init(interfaces ... )
            or
        upm_mixed_module_init(... REQUIRES interfaces)

d345006c03 cmake: Dependency refactoring for includes and libs
This commit attempts to use a more cmake-friendly approach when
handling inter-target dependencies.  A combination of macros and
include_directories usage provided overzealous compile -I/blah
entries which equates to large catch-all build commands.  For
example, the last CXX target contains include directories for nearly
all preceeding targets (~190).  Library dependencies were also often
wrong or missing.

    * Removed nearly all used of include_directories (swig cmake
      commands still appear to need these for generating the swig
      command line)
    * Updated usage of target_link_libraries in upm_module_init,
      also changed to using target_include_directories per target.
      This greatly simplifies upm/mixed_module_init usage for libraries
      which depend on other libraries (in this project).

        example (src/tb7300/CMakeLists.txt)
            old:
                 # upm-libbacnetmstp will bring in libbacnet, I hope
                 set (reqlibname "upm-bacnetmstp")
                 include_directories(${BACNET_INCLUDE_DIRS})
                 include_directories("../bacnetmstp")
                 upm_module_init()
                 upm_target_link_libraries(${libname} bacnetmstp)
            new:
                 upm_module_init(bacnetmstp)

      The reason here, is that tb7300 depends on bacnetmstp, which
      depends on BACNET includes/libs, so tb7300 gets the headers and
      libraries transitively via its dependency on bacnetmstp.
    * Updated pkg-config .pc file generation flow to reflect changes
      with dependencies.
    * Create a real target for the interfaces (CXX abstract sensor
      classes).  Renamed the directory from 'upm/src/upm' to
      'upm/src/interfaces'  Also changed the install location of the
      interface headers to include/upm/interfaces.  Updated interface
      header usage to reflect this.
    * Updated a few sensor libs to use fwd declarations for mraa.
      Ideally the UPM libs would do more of this which eases the
      burden on anyone building on top of the sensor libraries since
      they would not need to know about mraa headers.
    * Fixed examples which use symbols not defined in local includes

6241e20dda bmp280, bme280: Initial implementation
This library adds support for both the BMP280 and BME280 sesnors from
Bosch.  The BME is virtually identical to the BMP280 aside from some
slight register changes and adding support for a humidity sensor.

The BMP280 is an absolute barometric pressure sensor especially
designed for mobile applications. The sensor module is housed in an
extremely compact 8-pin metal-lid LGA package with a footprint of only
2.0 × 2.5 mm2 and 0.95 mm package height. Its small dimensions and its
low power consumption of 2.7 μA @1Hz allow the implementation in
battery driven devices such as mobile phones, GPS modules or watches.

The BME280 is as combined digital humidity, pressure and temperature
sensor based on proven sensing principles. The sensor module is housed
in an extremely compact metal-lid LGA package with a footprint of only
2.5 × 2.5 mm2 with a height of 0.93 mm. Its small dimensions and its
low power consumption allow the implementation in battery driven
devices such as handsets, GPS modules or watches. The BME280 is
register and performance compatible to the Bosch Sensortec BMP280
digital pressure sensor

These drivers support both I2C and SPI operation.

When using SPI on an Edison with the arduino breakout board, you
must specify a CS of -1 to the constructor, and connect the chip's
CS pin to arduino pin 10.
