setting variables for eclipse

MINGW_HOME = ${MSYS_HOME}\mingw64;

MSYS_HOME = FOLDER IN WHICH MSYS2 IS INSTALLED

PATH =
${MSYS_HOME}\usr\bin;
${MSYS_HOME}\usr\include;
${MSYS_HOME}\usr\lib;
${MINGW_HOME}\bin;
${MINGW_HOME}\include;
${MINGW_HOME}\lib;
${MINGW_HOME}\include\c++\10.3.0;
${MINGW_HOME}\x86_64-w64-mingw32\include;
${MINGW_HOME}\x86_64-w64-mingw32\lib;

after that you need to restart eclipse

after that it was found that eclipse ide c ++ compiles the cmake project normally, but at the same time it gives errors that it supposedly cannot find the header files

The editor uses an Indexer to learn definitions found in headers.
The Indexer is independent of the build system.

The Indexer uses various providers (scanners) to discover
where headers can be found. One of the providers gets
the definitions built into GCC.

The Indexer is configured using a dialog that, for whatever reason,
has been excluded from CMake projects. There is no documentation
describing how to accomplish the Indexer configuration or
how to run the equivalent of the built-in provider in a CMake projects.

My advice is to have CMake create a makefile
then use a Makefile project using that makefile.

I've discovered a setting in Window --> Preferences --> C/C++ --> CMake --> Indexer Support
labelled Show output of compiler built-in detection in the build console
Turn this on.

It seems to wait until the next build.
Afterward, I had to rebuild the index Project --> C/C++ Index --> Rebuild

It my be necessary to run the CMake GUI again Project-->Properties-->CMake
rerunning Configure and Generate

It isn't clear if it's necessary to enable the showing of the built-in detection
but it will definitely show when it is run.
