Hello Cygwinstas,
Cygwin root is C:\ix\cygwin, just so you know.
This is the output I see: mintty screen dump:
$ cmake -G"Unix Makefiles" C:/Users/somia/Downloads/libjpeg-turbo-3.1.1/
cmake -G"Unix Makefiles" C:/Users/somia/Downloads/libjpeg-turbo-3.1.1/

CMake Error at /usr/share/cmake/Modules/CMakeTestCCompiler.cmake:67 (message):
The C compiler
"/c/ix/cygwin/bin/cc"
is not able to compile a simple test program.
It fails with the following output:

If I clean out all cached data in my build dir and set `CC=/bin/gcc';
export CC' is get another error:

I hear people saying good things about CMake but this is maddening.
My cmake is newly installed in /usr/bin/cmake and is version 3.30.1
I'm trying to build libjpeg-turbo as my pathnames above would suggest.
