Unbreak CMake build on FreeBSD (#2209)

* cmake: unbreak on non-GNU after 474ada9267cc

CMake Error at CMakeLists.txt:121 (target_link_libraries):
  The keyword signature for target_link_libraries has already been used with
  the target "Hyprland".  All uses of target_link_libraries with a target
  must be either all-keyword or all-plain.

  The uses of the keyword signature are here:

   * CMakeLists.txt:107 (target_link_libraries)

Fixes https://github.com/hyprwm/Hyprland/issues/1780

* cmake: always link with dependencies via imported targets

On BSD systems base compiler by default only looks for headers and
libraries from base system. For dependencies from packages extra flags
are necessary.

ld: error: unable to find library -lxcb
ld: error: unable to find library -lpixman-1
ld: error: unable to find library -lOpenGL
ld: error: unable to find library -lGLESv2

* make: use same make in recursive calls

On BSDs `make` is BSD make while `gmake` is GNU make

* make: work around GNU vs. BSD sed -i incompatibility

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=254091

* make: replace GNU make extension with POSIX sh

`$(shell ...)` in GNU make is similar to `${:!..!}` in BSD make

* make: fall back when nproc isn't available

Only FreeBSD added nproc for compatibility with Linux.

* make: unbreak hyprctl on Clang-based systems

/bin/sh: g++: not found
error: invalid value 'c++23' in '-std=c++23'

* make: create lib/ before copying libwlroots.so there

$ make install PREFIX=/tmp/test
[...]
cp: directory /tmp/test/lib does not exist

* make: pass cp(1) flags before arguments

cp: -f is not a directory

* make: replace install -Dt with mkdir

install: illegal option -- t

* make: replace cp --parents with cpio -dump

cp: illegal option -- -

* make: limit pkg-config workaround to Linux when run as root

/usr/share/pkgconfig doesn't exist on BSDs or may not be writable.
