origin/main does not compile anymore for Debug

[Ingo]

Describe the bug

Since months in my cmake project I successful downloaded and configured Googletest with:

include(FetchContent)

FetchContent_Declare(
    googletest
    GIT_REPOSITORY    https://github.com/google/googletest.git
    GIT_TAG           origin/main
    GIT_SHALLOW       ON
}
FetchContent_MakeAvailable(googletest)

Then I configure it with:

~$ cmake -S . -B build -D BUILD_SHARED_LIBS=ON -D CMAKE_BUILD_TYPE=Debug
~$ cmake --build build --config Debug

Now I get the error message:

gmake: *** [Makefile:149: all] Error 2

If I use in FetchContent_Declare():

GIT_TAG           release-1.11.0

then everything is successful working as before.

Can you please tell me the GIT_TAG of the previous origin/main release?

It looks like you are adding a debug suffix to the names of libraries, for example https://github.com/upnplib/upnplib/blob/57af560f5c4c0e71ef8655117a7e8e47c71dab37/CMakeLists.txt#L337. We recently removed the debug suffix.

Instead of hardcoding the file names, I think CMake lets you refer to them by something like GTest::gmock.
