When I ran the command on step 3 of compilation cmake . -DCMAKE_INSTALL_PREFIX=[installation prefix] -DCMAKE_CXX_COMPILER=[C++ compiler] CXXFLAGS=[C++ compiler flags] (filling in my information), I get the error:
The source directory "/path/to/libint2/libint-2.6.0/CXXFLAGS=-O3" does not exist.
I think CXXFLAGS needs to be replaced with -DCMAKE_CXX_FLAGS. That fixed it for me at least!

I tried building the libint v2.6.0 pre-generated library ("lmax=6 library (standard ints only)") following the instructions in the Wiki at https://github.com/evaleev/libint/wiki#configuring-and-building-libint-library-version-260-and-higher, but ran into an issue while compiling with cmake.
