Build script won't find libuInputPlus and libevdevPlus for linking

[depau]

Hi,
please see this comment reported on the Arch Linux AUR package:

https://aur.archlinux.org/packages/ydotool-git/#comment-710452

User reports the following linking issue, which I was able to reproduce in a clean Docker container:

[100%] Linking CXX executable ydotool_static
/usr/bin/ld: cannot find -luInputPlus
/usr/bin/ld: cannot find -levdevPlus
/usr/bin/ld: libydotool.a(Tool.cpp.o): in function `ydotool::Tool::ToolManager::TryDlOpen(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)':
Tool.cpp:(.text+0x20e): warning: Using 'dlopen' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking
/usr/bin/ld: cannot find -luInputPlus
/usr/bin/ld: cannot find -levdevPlus
collect2: error: ld returned 1 exit status

I believe it's an issue with the build scripts, but I couldn't find anything weird.

See the following asciinema for an example of a container build: https://asciinema.org/a/yJKDNWfhzs83xGHGMDkX0Pp2L

It's pretty much this:

pacman -Syu base-devel git sudo
useradd -m -G wheel user
visudo
## (enable passwordless sudo for wheel users)
su - user
git clone https://aur.archlinux.org/yay-bin.git
cd yay-bin
makepkg
sudo pacman -U yay-bin*.pkg.*
yay -S ydotool-git

It looks like, it's trying to statically link those libraries. At least for the AUR libraries, the static library files don't exist. That explains the error I guess:

[ 42%] Linking CXX executable ydotool_static
/usr/bin/cmake -E cmake_link_script CMakeFiles/ydotool_client_static.dir/link.txt --verbose=1
/usr/bin/c++  -march=x86-64 -mtune=generic -O2 -pipe -fno-plt -O3 -DNDEBUG  -Wl,-O1,--sort-common,--as-needed,-z,relro,-z,now -rdynamic CMakeFiles/ydotool_client_static.dir/Client/ydotool.cpp.o  -o ydotool_static -L. libydotool.a -lboost_program_options -lpthread -luInputPlus -levdevPlus -static -ldl -lboost_program_options -luInputPlus -levdevPlus

This should be fixed in 710e77f

Hi, I tested it and now it builds.
Thank you :)

This is now broken again. I've tried to build it on openSUSE using cmake. In my case it's missing boost_program_options:
/usr/lib64/gcc/x86_64-suse-linux/10/../../../../x86_64-suse-linux/bin/ld: cannot find -lboost_program_options

The
set_target_properties(... PROPERTIES EXCLUDE_FROM_ALL TRUE)
line has gone missing from CMakeLists.txt. If I add it for all targets, it compiles.
