Your "pkg-config.exe" program is found in the path and it finds several 
mandatory packages as glib and gthread, so it seems to work properly anyway.

libsndfile and portaudio are both optional and independent. You don't need to 
worry if you don't need their functionality.

Yes, you need to solve several issues.

No problem with the above checks. Many headers only exist on Unix or other 
platforms...

... While other headers exist also on Windows.

There is a problem here. I've included a check for three keywords trying to 
find which one is needed for inlining functions, but looks like none is 
supported in VS10. In VS9, "__inline" works, but maybe the check is wrong or 
we need to include another keyword.

Another problem here. This test is implemented by CMake and works in VS9. 
Maybe the VC compiler is not working properly.

This needs to be fixed, obviously.

This header comes from the DirectX SDK. You need the DirectX runtime to run 
FluidSynth on Windows, and the DirectX SDK to compile it or at least 
the "dsound.h" header.

This means that pkg-config works and finds some mandatory packages.

These packages aren't mandatory. They can be optionally included in windows 
build, if they are found using pkg-config.

Some of the failing checks suggest that the compiler is not working properly. 
I'm not sure about the root cause. Maybe you need to check some environment 
variables required by the compiler. The proper environment for VS compilers 
is provided by a start menu shortcut labeled "Visual Studio XXXX command 
prompt" (or something like that), that opens a cmd.exe window using a .bat 
script. Can you try running cmake-gui from this command prompt and see if 
there is some difference?
