[cgal] ctest does not recognise tests when cgal lib included

[JeffreyWardman]

To Reproduce
Using cmake-init template with and without:

find_package(CGAL CONFIG REQUIRED)
target_link_libraries(main PRIVATE CGAL::CGAL)

Running cd target/build && ctest --output-on-failure -j16 && cd ../.. says no tests are found if a simple main is added which includes cgal in any way.

Using the latest version of vcpkg for local installation does not reproduce the issue.

Please try this demo that use its dependency mpfr by find cgal:

cmake_minimum_required(VERSION 3.25.1)
project(Test VERSION 0.1.2.3 LANGUAGES CXX)

add_executable(main c.cpp)
target_compile_features(main PRIVATE cxx_std_23)

find_package(CGAL CONFIG REQUIRED)
target_link_libraries(main PRIVATE CGAL::CGAL)

#include "CGAL/version.h"
#include "mpfr.h"

#include <iostream>

int main() {
    std::cout << "cgal version:\t" << CGAL_VERSION_STR << std::endl;
    std::cout << "mpfr version:\t" << mpfr_get_version() << std::endl;
    return 0;
}
