Building UPM {#building}
============
UPM uses cmake in order to make compilation relatively painless. Cmake runs
build out of tree so the recommended way is to clone from git and make a build/
directory.
UPM will attempt to build all directories inside src/ and they must contain
individual CMakeLists.txt files.
~~~~~~~~~~~~~{.sh}
mkdir build
cd build
cmake ..
make
~~~~~~~~~~~~~
Our cmake configure has a number of options, `cmake -i` will ask you all sorts
of interesting questions, you can disable swig modules, build documentation
etc...
Few recommended options:
Changing install path from /usr/local to /usr
-DCMAKE_INSTALL_PREFIX:PATH=/usr
Building debug build:
-DCMAKE_BUILD_TYPE=DEBUG
Using clang instead of gcc:
-DCMAKE_C_COMPILER=/usr/bin/clang -DCMAKE_CXX_COMPILER=/usr/bin/clang
