### Select the build type
# Use Release/Devel/Debug : -DCMAKE_BUILD_TYPE=Release|Devel|Debug
# Enable/disable the stipping : -DCMAKE_BUILD_STRIP=TRUE|FALSE
### Force the choice of 3rd party library in pcsx2 over system libraries
# Use all internal lib: -DFORCE_INTERNAL_ALL=TRUE
# Use soundtouch internal lib: -DFORCE_INTERNAL_SOUNDTOUCH=TRUE
# Use zlib internal lib: -DFORCE_INTERNAL_ZLIB=TRUE
# Use sdl1.3 internal lib: -DFORCE_INTERNAL_SDL=TRUE # Not supported yet
### Miscellaneous
# Select install dir of l10n : -DL10N_PORTABLE=TRUE(bin/Langs)|FALSE(FHS, /usr...)
### Add some flags to the build process
# control C flags : -DUSER_CMAKE_C_FLAGS="cflags"
# control C++ flags : -DUSER_CMAKE_CXX_FLAGS="cxxflags"
# control link flags : -DUSER_CMAKE_LD_FLAGS="ldflags"
