   4 Subject: [PATCH] cmake: Only use relative paths for install DESTINATION option
   5  (#1405)
   6
   7 As described in #1404, the explicit use of CMAKE_INSTALL_PREFIX conflicts with using command-line --prefix.
   8
   9 This simply removes all explicit use of CMAKE_INSTALL_PREFIX.
  10
  11 Otherwise this path will be duplicated:
  12
  13     $ cmake -DCMAKE_BUILD_TYPE=debug -DCMAKE_EXPORT_COMPILE_COMMANDS=ON -DCMAKE_INSTALL_PREFIX=inst ..
  14     $ DESTDIR=inst ninja install
  15     ...
  16     -- Installing: inst/src/le/libevent/.cmake-debug/inst/include/event2/util.h
  17     -- Installing: inst/src/le/libevent/.cmake-debug/inst/include/event2/ws.h
  18     ...
  19
  20 Fixes: #1404
