How to install the lib ?

[tetsuhaut]

Until recently (something like version 2.0.2), when building the lib, it was possible to install it using ninja install
With the 2.1.1 version, ninja install doesn't work as there is no install target anymore.
The consequence is that because the lib is not installed, in my CMakeLists.txt file the instruction find_package(stlab 2.1.1 REQUIRED) produces the error

CMake Error at CMakeLists.txt:254 (find_package):
  By not providing "Findstlab.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "stlab", but
  CMake did not find one.

  Could not find a package configuration file provided by "stlab" (requested
  version 2.1.1) with any of the following names:

    stlabConfig.cmake
    stlab-config.cmake

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

Looking in the lib build dir, there is no such file. What are we supposed to do in order to use this library?

The install was getting problematic to maintain as I refactor the library into smaller components (such as copy-on-write and enum-ops). I'm adding the following to the Readme.

Using the STLab Libraries

The recommended approach to using the libraries is to use CPM and add the following to your CMakeLists.txt:

CPMAddPackage("gh:stlab/libraries@2.1.1")

(replace 2.1.1 with the desired version).

OK, I guess it's the same reason why

find_package(stlab 2.1.2 REQUIRED)
target_link_libraries(mainLib PRIVATE stlab::stlab)
target_link_libraries(unitTests PRIVATE stlab::stlab)

in my project CMakeLists.txt doesn't work anymore ?

Yes - you could use FetchContent, but CPM is a simpler approach.
