Cmake Strange Error: Syntax Error Unexpected Token ('

I am compiling Qt5, VTK, PCL, and PDAL into a project, and my build process was working excellently until I rebuilt PCL because I was trying to get rid of another weird error where syntax errors kept popping up in Qt5 after linking PCL. For more info on that, see here: Qt, VTK, PCL, and PDAL integration I also recently agreed to a new XCode License under root. So that may also be the problem. Here is the exact error:

/bin/sh: -c: line 0: syntax error near unexpected token `('
/bin/sh: -c: line 0: `/usr/bin/g++   -DQT_CORE_LIB -DQT_GUI_LIB -DQT_NO_DEBUG -DQT_WIDGETS_LIB -I/Users/wfehrnstrom/build-CmakeTest-MainKit-Release -I/Users/wfehrnstrom/CmakeTest -I/usr/local/include/vtk-7.0 -isystem /usr/local/include -iframework /Users/wfehrnstrom/Qt5/5.7/clang_64/lib -isystem /Users/wfehrnstrom/Qt5/5.7/clang_64/lib/QtWidgets.framework/Headers -isystem /Users/wfehrnstrom/Qt5/5.7/clang_64/lib/QtGui.framework/Headers -isystem /System/Library/Frameworks/OpenGL.framework/Headers -isystem /Users/wfehrnstrom/Qt5/5.7/clang_64/lib/QtCore.framework/Headers -isystem /Users/wfehrnstrom/Qt5/5.7/clang_64/./mkspecs/macx-clang  -ferror-limit=0 -O3 -DNDEBUG   vtkDomainsChemistry_AUTOINIT=1(vtkDomainsChemistryOpenGL2) vtkRenderingContext2D_AUTOINIT=1(vtkRenderingContextOpenGL2) vtkRenderingCore_AUTOINIT=3(vtkInteractionStyle,vtkRenderingFreeType,vtkRenderingOpenGL2) vtkRenderingVolume_AUTOINIT=1(vtkRenderingVolumeOpenGL2) -fPIC -std=gnu++11 -o CMakeFiles/CmakeTest.dir/main.cpp.o -c     /Users/wfehrnstrom/CmakeTest/main.cpp'
make[2]: *** [CMakeFiles/CmakeTest.dir/main.cpp.o] Error 2
make[1]: *** [CMakeFiles/CmakeTest.dir/all] Error 2

Does anyone know why I am getting this strange error seemingly out of nowhere after rebuilding VTK and PCL? Thank you!

Had this exact same issue when pulling PCL into QT5 on OS X.

Compiling PCL 1.8 from source resolved the issue (migrated from PCL 1.6).

CMakeLists.txt:

project(LRS_PCL)
set(CMAKE_C_COMPILER "/usr/bin/gcc")
set(CMAKE_CXX_COMPILER "/usr/bin/g++")
cmake_minimum_required(VERSION 2.8)

set(SOURCE_DIR .)
set(SOURCE
   ${SOURCE}
   ${CMAKE_CURRENT_SOURCE_DIR}/main.cpp
   PARENT_SCOPE
)
aux_source_directory(. SRC_LIST)
add_executable(${PROJECT_NAME} ${SRC_LIST})
set(CMAKE_PREFIX_PATH $ENV{HOME}/Qt/5.5/gcc_64)

find_package( PCL 1.8 REQUIRED )
find_package( Qt5 REQUIRED COMPONENTS Widgets Core )

include( CheckCXXCompilerFlag )
set( CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11" )

include_directories( ${PCL_INCLUDE_DIRS} /user/local/include )
link_directories( ${PCL_LIBRARY_DIRS} /usr/local/lib /usr/lib/x86_64-linux-gnu )
add_definitions( ${PCL_DEFINITIONS} )

target_link_libraries( LRS_PCL ${PCL_LIBRARIES} /usr/local/lib/librealsense.so )
