Compilation error and solution on High Sierra

Compilation fails on High Sierra.

Error:

CMake Error at heimdall-frontend/CMakeLists.txt:53 (install):
  install TARGETS given no BUNDLE DESTINATION for MACOSX_BUNDLE executable
  target "heimdall-frontend".

The issue is already fixed in this pull request that was not merged:

https://github.com/Benjamin-Dobell/Heimdall/pull/462

To get compilation to work before this is merged, manually patch heimdall-frontend/CMakeLists.txt with:

diff --git a/heimdall-frontend/CMakeLists.txt b/heimdall-frontend/CMakeLists.txt
index 05a9e75..6614a44 100644
