[Paraview] Passing group of flags to all TUs

[Gonzalo Brito Gadeschi]

I'm trying to install paraview from source using:

CC=clang CXX=clang++ CXXFLAGS="-nostdinc++ -stdlib=libc++
-I${LIBCXX_INCLUDE} -L${LIBCXX_LIB}" cmake $PV_SRC \
    -DBUILD_DOCUMENTATION:BOOL=ON \
    -DBUILD_SHARED_LIBS:BOOL=ON \
    -DCMAKE_BUILD_TYPE:STRING=Release \
    -DCMAKE_INSTALL_PREFIX:PATH=$PREFIX \
    -DPARAVIEW_ENABLE_PYTHON:BOOL=ON \
    -DPARAVIEW_INSTALL_DEVELOPMENT_FILES:BOOL=ON \
    -DPARAVIEW_USE_MPI:BOOL=ON \
    -DPARAVIEW_ENABLE_FFMPEG:BOOL=ON \
    -DVTK_SMP_IMPLEMENTATION_TYPE:STRING=TBB \
    -DCMAKE_CXX_FLAGS="-nostdinc++ -stdlib=libc++ -I${LIBCXX_INCLUDE}
-L${LIBCXX_LIB}" \
    -DMPI_CXX_COMPILE_FLAGS="-nostdinc++ -stdlib=libc++ -I${LIBCXX_INCLUDE}
-L${LIBCXX_LIB}"

Everything works fine up to the point where it tries to compile
VTK/ThirdParty/netcdf:

make[1]: *** Waiting for unfinished jobs....
A make VERBOSE=1 reveals that CMake does not pass the CXXFLAGS I've
specified when compiling netcdf.cpp. Since the include directories of the
standard library are missing, compilation fails.

Am I setting the compilation flags correctly (CXXFLAGS, DCMAKE_CXX_FLAGS,
DMPI_CXX_FLAGS..) ?

How do I pass a group of flags to all translation units?
