Hi,
I do have Visual Studio 2017 and Visual Studio 2019 installed side by side on my workstation.
To compile a third product used in my application, I used to do:
call "C:\Program Files (x86)\Microsoft Visual Studio\2019\\Community\VC\Auxiliary\Build\vcvarsall.bat" x86
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE:STRING=Release -A Win32 -Thost=x64 -g "Visual Studio 16 2019" -DCMAKE_GENERATOR_INSTANCE:STRING="C:\Program Files (x86)\Microsoft Visual Studio\2019\Community" ..
Unfortunately, in the cmake output log, I can see that there is something wrong, since cmake claims it is using Visual Studio 15 2017, while the C and C++ compilers match Visual Studio 2019.
-- Building for: **Visual Studio 15 2017**

Unfortunately, setting -DCMAKE_GENERATOR_INSTANCE to the Visual Studio 2019 did not help.
Is this a known issue ?
Thanks for your valuable feedback
