* add build time dependency to static lib the header only fmt lib is used to show this * use add_test() and add a warning why doctest_discover_tests() is only availabe if doctest is not imported with find_packag() * cmake-format file * fix missed comment * back to version 1.0 respect most review comments * fix typo * update used CMP package versions * respect most review comments no default cxx language settings install fmt link against fmt::fmt export dependency too if not needed ... * use generic expression as recommended * Update CMakeLists.txt Co-authored-by: Lars Melchior <TheLartians@users.noreply.github.com> * changes acording review comments update to current PackageProject version 1.5.0 too * Update CMakeLists.txt Co-authored-by: Lars Melchior <TheLartians@users.noreply.github.com> * respect review comment remove NOLINT comment * back to begining needs to use doctest cmake modules ... it is not my idea!
