Repeated cmake development builds are broken #23586
Description
Reproduction:
Run (with a clean checkout or at least after cleaning cmake/build directory).
tools/run_tests/run_tests.py -l c -c dbg --build_only --compiler cmake
which succeeds.
Right after that, run the same command again
tools/run_tests/run_tests.py -l c -c dbg --build_only --compiler cmake
This time if fails with an error
cmake -DgRPC_BUILD_TESTS=OFF -DCMAKE_BUILD_TYPE=Release ../..
CMake Error at third_party/abseil-cpp/CMake/AbseilHelpers.cmake:350 (message):
ABSL: compiling absl requires a gtest CMake target in your project,
see CMake/README.md for more details
Call Stack (most recent call first):
third_party/abseil-cpp/CMakeLists.txt:105 (check_target)
E. g. "tests/run_tests.py -l csharp --build_only" behaves the same
