Too bad NAG put spaces in their internal pathnames. Ugh. I suggest you report that issue to them since it gratuitously creates problems for those building free software packages such as PLplot. Here is another possible workaround for this situation. I presume you are working with either Cygwin or MinGW-w64/MSYS2 which have their own non-NAG versions of pkg-config, freetype, etc., available. If so, put "D:\NAG\EFBuilder 6.1\bin" at the end of the PATH and not the start. The result should be that the non-NAG version of pkg-config is found and that, in turn, should find the non-NAG version of freetype. This idea is based on the assumption that the NAG software installation does not fiddle with the PKG_CONFIG_PATH environment variable, but there are ways to get around that if necessary. The other assumption I am using here is NAG supplies pkg-config, freetype (and presumably its own versions of other useful build tools and libraries) for customer convenience and not as a necessity for the NAG compiler to work properly. (If the NAG compiler relied directly on certain free software tools and libraries, i.e., this is more than just providing a convenience for customers, then there might be a version mismatch issue if you substituted Cygwin or MinGW-w64/MSYS2 versions of tools and free libraries for NAG ones.) With regard to the eventual build-system fix for spaces in pathnames, I have been doing a lot of further investigation, and one of the primary issues is that our build system uses the COMPILE_FLAGS property virtually everywhere (since that was the only way to work with compiler flags in CMake a decade ago.) That property is a space-separated string containing the various compiler flags, and that makes it difficult/impossible to distinguish spaces in the various parts of that string from the spaces that are supposed to separate those parts. It turns out that CMake-3 deprecates COMPILE_FLAGS (presumably for that space-separated reason) and instead provides the COMPILE_OPTIONS choice which stores its results in a normal CMake list. It is a big undertaking for me to change our build system so that it uses COMPILE_OPTIONS rather than COMPILE_FLAGS and processes those results with normal CMake list processing rather than special code to deal with the space separation. However, I believe that massive cleanup to our build system will be worth it since I am pretty sure many of our problems with spaces in path names will disappear as a result.
