nc-config references libraries which do not exist

[kevinushey]

I tried building netcdf with:

cmake -B build -S .
cd build
cmake --build .

This produces a nc-config file that has:

libsprivate="-lHDF5::HDF5 -lhdf5::hdf5_hl -lm -lz -lzip -lzstd -lbz2 -lsz -lCURL::libcurl -lxml2"

I suspect those library paths, e.g. -lHDF5::HDF5, are just the raw CMake directives. Do those need to be expanded into "real" library paths before generating nc-config?

I guess the presence of

netcdf-c/nc-config.cmake.in

Lines 361 to 374 in 95a6361

	--libs-ac-syntax)
	libs=$(echo $libs | sed 's/hdf5::hdf5_hl/hdf5_hl/g')
	libs=$(echo $libs | sed 's/HDF5::HDF5/hdf5/g')
	if [ "x$HAS_STATIC" = "xTRUE" ]; then
	libsprivate=$(echo $libsprivate | sed 's/hdf5::hdf5_hl/hdf5_hl/g')
	libsprivate=$(echo $libsprivate | sed 's/HDF5::HDF5/hdf5/g')
	echo $libs $libsprivate
	else
	echo $libs
	fi
	;;

mean this is intentional, and I should instead be using --libs-ac-syntax? But then you get:

$ ./nc-config --static --libs-ac-syntax
-L/usr/local/lib -lnetcdf -lHDF5::HDF5 -lhdf5::hdf5_hl -lm -lz -lzip -lzstd -lbz2 -lsz -lCURL::libcurl -lxml2
-L/usr/local/lib -lnetcdf -lhdf5 -lhdf5_hl -lm -lz -lzip -lzstd -lbz2 -lsz -lCURL::libcurl -lxml2

Two lines are logged, and CURL::libcurl remains unreplaced in the second output.
