I really need to add # in Cmake url but BYPRODUCTS containing a "#" is not allowed

Code in CMakeLists.txt

if (NOT glad_FOUND)
    include(FetchContent)
    FetchContent_Declare(
            glad
            URL "https://glad.dav1d.de/#language=c&specification=gl&api=gl%3D4.6&api=gles1%3Dnone&api=gles2%3Dnone&api=glsc2%3Dnone&profile=compatibility&loader=on"
            DOWNLOAD_NO_EXTRACT TRUE

    )
    FetchContent_MakeAvailable(glad)
endif()

Url

Error:

CMake Error at D:/IDEs/apps/CLion/ch-0/222.4167.35/bin/cmake/win/share/cmake-3.23/Modules/ExternalProject.cmake:2302:EVAL:2 (add_custom_command): BYPRODUCTS containing a "#" is not allowed.

Solution

Im switched to GLEW

find_package(GLEW QUIET)
if (NOT GLEW_FOUND)
    include(FetchContent)
    FetchContent_Declare(
            GLEW
            GIT_REPOSITORY https://github.com/Perlmint/glew-cmake
            GIT_TAG glew-cmake-2.2.0
    )
    FetchContent_MakeAvailable(GLEW)
endif ()
