Using ABSEIL from PROTOBUF

[drppetrov]

I managed to config and build ABSEIL. However, trying to build PROTOBUF nexts causing an issue:

CMake Error at D:/SIGNET/C++/abseil-cpp-master-bin/abslConfig.cmake:32 (include):
  include could not find requested file:

    XXX/abseil-cpp-master-bin/abslTargets.cmake
Call Stack (most recent call first):
  cmake/abseil-cpp.cmake:36 (find_package)
  CMakeLists.txt:339 (include)


CMake Error at XXX/abseil-cpp-master-bin/abslConfig.cmake:32 (include):
  include could not find requested file:

      XXX/abseil-cpp-master-bin/abslTargets.cmake
Call Stack (most recent call first):
  third_party/utf8_range/CMakeLists.txt:27 (find_package)

Note: XXX above is just to hide the absolute path on my sys (not relevant)

I checked and indeed there is no: abseil-cpp-master-bin/abslTargets.cmake
instead the file is located at: abseil-cpp-master-bin/CMakeFiles/abslTargets.cmake

Any idea what the solution for that is?
I see that ABSEL is using: include ("${CMAKE_CURRENT_LIST_DIR}/abslTargets.cmake") , which is something I never used myself to list files "${CMAKE_CURRENT_LIST_DIR}, could that be it?

Here is my entire build script:

SET MSBUILD="C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Auxiliary\Build\vcvarsamd64_x86.bat"

CALL %MSBUILD%
