#Todo:
#* add external cmake projects to source array and patch src/externla/*.cmake
#* use system wide: levmar, libigl, structyresynth, libe57, u3d, tinygltf

#Configuration:
#Use: makepkg VAR1=0 VAR2=1 to enable(1) disable(0) a feature
#Use: {yay,paru} --mflags=VAR1=0,VAR2=1
#Use: aurutils --margs=VAR1=0,VAR2=1
#Use: VAR1=0 VAR2=1 pamac

# Use CMAKE_FLAGS=xxx:yyy:zzz to define extra CMake flags
