CMake XCode build on macOS fails

[romanp-nexusgroup]

I am trying to build latest crypto++ with CMake generated XCode project

macOS 10.12.3
XCode 8.2.1
cmake version 3.7.2
mkdir build
cd build
cmake -G Xcode ..
open cryptopp.xcodeproj
build

Getting following error:

echo "Creating symlinks"
Creating symlinks
/usr/local/Cellar/cmake/3.7.2/bin/cmake -E cmake_symlink_library /Users/user1/dev/cryptopp/build/Debug/libcryptopp.5.7.dylib /Users/user1/dev/cryptopp/build/Debug/libcryptopp.5.7.dylib /Users/user1/dev/cryptopp/build/Debug/libcryptopp.dylib
CMake Error: cmake_symlink_library: System Error: No such file or directory

I commented out a part of makefile that sets SOVERSION, this helped

-       if (BUILD_SHARED)
-               set_target_properties(cryptopp-shared
-                               PROPERTIES
-                               SOVERSION ${COMPAT_VERSION}
-                               OUTPUT_NAME cryptopp)
-       endif()
+       #if (BUILD_SHARED)
+       #       set_target_properties(cryptopp-shared
+       #                       PROPERTIES
+       #                       SOVERSION ${COMPAT_VERSION}
+       #                       OUTPUT_NAME cryptopp)
+       #endif()

But not for long, then I got this:

Ld build/Debug/cryptest.exe normal x86_64
    cd /Users/user1/dev/cryptopp
    export MACOSX_DEPLOYMENT_TARGET=10.12

clang: error: no such file or directory: '/Users/user1/dev/cryptopp/build/Debug/libcryptopp.a'

cryptest wants to link to static library and it wants it to be named libcryptopp.a, but XCode thinks otherwise. XCode produces a file build/cryptopp.build/Debug/cryptopp-object.build/Objects-normal/libcryptopp-object.a

At this point I am not sure what I need to change to make it work, the makefile looks too complicated for me

Setting USE_INTERMEDIATE_OBJECTS_TARGET to OFF makes XCode happy

echo "Creating symlinks" is kind of weird because we don't create symlinks.

Its probably more Cmake goodness. It may be related to Issue 355: CMake-based Xcode build fails to build any library.

Looks like it is the case. Thank you!

Last call for CMake patches before removing it from the library and adding it to the patch page. If you have something to add, then now is the time to do it.
