Cannot build the project with cmake fetchContent

[billcxx]

I can compile Ecl on the same machine with the normal git clone and cmake process, but I cannot compile Ecl if it is included by fetchContent as follows

FetchContent_Declare(
  ecl
  GIT_REPOSITORY https://github.com/equinor/ecl.git
  GIT_SUBMODULES ""
  GIT_TAG 2.14.0)
FetchContent_MakeAvailable(ecl)

When I try to configure my project, I met an error during

CMake Error at build/x64-gnu-Debug/_deps/ecl-src/lib/CMakeLists.txt:182 (set_target_properties):
  set_target_properties called with incorrect number of arguments.

Here is full output to the console

I notice the difference between the normal build process and the fetchContent process is these two lines

The problem is in the root CMakeLists.txt file, line 128 to line 132.
The ${CMAKE_SOURCE_DIR} is my own projects directory rather than the populated Ecl directory.

128     execute_process(
129       COMMAND ${GIT_EXECUTABLE} "--git-dir=${CMAKE_SOURCE_DIR}/.git" describe
