boost::dll doesn't seem to install with cmake on version 1.89

[bgemmill]

This report is duplicated here as per @pdimov in the original.

I tried moving to boost 1.89 from 1.88 this afternoon, and found with the cmake installer that boost::dll doesn't seem to get installed with the newest version.

With boost 1.88, the cmake build output would contain lines like:

[build] -- Installing: /<relative-build-path>/boost/include/boost/dll/detail/posix/shared_library_impl.hpp

But 1.89 doesn't seem to have any.

This can be reproduced with:

git clone --recurse-submodules https://github.com/boostorg/boost --depth 1
cd boost
mkdir build
mkdir install
cd build
cmake -DCMAKE_INSTALL_PREFIX=../install ..
cmake --build . --target install -j
cd ../install/include/boost
cd dll # No such file or directory

Did something happen to how the dll project uses cmake between version 1.88 and 1.89?

[pdimov]

As I said in boostorg/cmake#84, it looks like #100 broke things.

If you're going to make changes to the CMakeLists.txt file, you need CI that tests installation (and ideally also CI that tests add_subdirectory use.)

I still think that the original change is wrong. See discussion in #94.
