As this is a C program, set
pclmtoraster_CFLAGS, not pclmtoraster_CXXFLAGS.
This fixes building pclmtoraster when libcupsfilter headers are installed in a non-standard directory.
Previously, when configuring and installing libcupsfilters with e.g. --prefix=$HOME/temp/cpdb and then configuring cups-filters with PKG_CONFIG_PATH=$HOME/temp/cpdb/lib/pkgconfig/, make pclmtoraster would fail like this:
CC filter/pclmtoraster.o
filter/pclmtoraster.c:14:10: fatal error: cupsfilters/filter.h: No such file or directory
14 | #include <cupsfilters/filter.h>
| ^~~~~~~~~~~~~~~~~~~~~~
compilation terminated.
For this to actually work, recent libcupsfilters
commit [1] is also needed:
