Bug Description

-- Building xtensor v0.25.0
CMake Error at vendor/xtensor/CMakeLists.txt:42 (find_package):
  By not providing "Findxtl.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "xtl", but
  CMake did not find one.

  Could not find a package configuration file provided by "xtl" (requested
  version 0.7.5) with any of the following names:

    xtlConfig.cmake
    xtl-config.cmake

  Add the installation prefix of "xtl" to CMAKE_PREFIX_PATH or set "xtl_DIR"
  to a directory containing one of the above files.  If "xtl" provides a
  separate development package or SDK, be sure it has been installed.

Git submodules are in place. What is wrong?

Steps to Reproduce

configure

I also tried to replace xtensor with its latest release and it compilation fails.

Environment

Version 0.15.3
FreeBSD 15 STABLE
