Liu Dongmiao 51752fa14b libevent2: make cmake use relative imported path
libevent2's cmake use absolute path, then cmake cannot find it when cross compiling:

```
-- Found libevent include directory: /builder/staging_dir/target-mips_24kc_musl/usr/include
-- Found libevent component: /builder/staging_dir/target-mips_24kc_musl/usr/lib/libevent_core.so
-- Found libevent component: /builder/staging_dir/target-mips_24kc_musl/usr/lib/libevent_extra.so
-- Found libevent component: /builder/staging_dir/target-mips_24kc_musl/usr/lib/libevent_openssl.so
-- Found libevent 2.1.12 in /builder/staging_dir/target-mips_24kc_musl/usr
CMake Error at /builder/staging_dir/target-mips_24kc_musl/usr/lib/cmake/libevent/LibeventTargets-shared.cmake:102 (message):
  The imported target "libevent::core" references the file

     "/usr/lib/libevent_core-2.1.so.7.0.1"

  but this file does not exist.  Possible reasons include:

  * The file was deleted, renamed, or moved to another location.

  * An install or uninstall procedure did not complete successfully.

  * The installation package was faulty and contained

     "/builder/staging_dir/target-mips_24kc_musl/usr/lib/cmake/libevent/LibeventTargets-shared.cmake"

  but not all the files it references.

Call Stack (most recent call first):
  /builder/staging_dir/target-mips_24kc_musl/usr/lib/cmake/libevent/LibeventConfig.cmake:168 (include)
  CMakeLists.txt:34 (find_package)
```

This patch make cmake use relative imported path, so it can find libevent.

Subject: [PATCH] cmake: Only use relative paths for install DESTINATION option
(#1405)
As described in #1404, the explicit use of CMAKE_INSTALL_PREFIX conflicts with using command-line --prefix.
This simply removes all explicit use of CMAKE_INSTALL_PREFIX.
Otherwise this path will be duplicated:
$ cmake -DCMAKE_BUILD_TYPE=debug -DCMAKE_EXPORT_COMPILE_COMMANDS=ON -DCMAKE_INSTALL_PREFIX=inst ..
$ DESTDIR=inst ninja install
...
-- Installing: inst/src/le/libevent/.cmake-debug/inst/include/event2/util.h
-- Installing: inst/src/le/libevent/.cmake-debug/inst/include/event2/ws.h
...
Fixes: #1404
