I am not sure if it's a vaild command for FetchContent_Declare, but it is available in ExternalProject_Add. For more: https://discourse.cmake.org/t/fetchcontent-declare-with-cmake-args-does-not-work/11227/2

FetchContent_MakeAvailable(moab)
add_subdirectory(${moab_SOURCE_DIR} ${moab_BINARY_DIR}) # MOAB repository is not properly configured for a FetchContent build
# Set MOAB_DIR to the fetched content
set(MOAB_DIR ${moab_SOURCE_DIR})
