Re: [fluid-dev] pkgconfig not found

[Tom M.]

It uses c++ as linker? No matter 1.1.6, 1.1.7 or master? Shouldnt happen. I 
think it's time for a full build log:

cmake -DCMAKE_VERBOSE_MAKEFILE=1 ..
make > build.log

You can try setting these cmake variables to gcc.exe
CMAKE_LINKER
CMAKE_C_LINK_EXECUTABLE
CMAKE_CXX_LINK_EXECUTABLE

But this is exactly how cross platform deployment works. I dont understand why 
you want to bundle all audio drivers (even foreign ones) in a single dll. Think 
about it: How would you compile fluidsynth with ALSA or OSS support on windows? 
The ABI and calling conventions between different OSs vary. I dont see how this 
could work.

And unless you want to privately fork fluidsynth, writing a custom makefile is 
IMO the worst choice you could make. If upstream changes anything related to 
the buildsystem your build will break.
