Revision 61c60b239c0ddc5eb975bb9cc3721b792a2aa18f authored by Stephen Kelly on 12 March 2014, 15:58:03 UTC, committed by Stephen Kelly on 17 March 2014, 13:15:14 UTC
Override the QT_QTMAIN_LIBRARY cache variable with a regular variable in the Qt 5 configuration. This avoids linking with the Qt 4 version of the WinMain library.

# FindProtobuf
# ------------
#
#
#
# Locate and configure the Google Protocol Buffers library.
#
# The following variables can be set and are optional:
#
# ::
#
# PROTOBUF_SRC_ROOT_FOLDER - When compiling with MSVC, if this cache variable is set
# the protobuf-default VS project build locations
# (vsprojects/Debug & vsprojects/Release) will be searched
# for libraries and binaries.
#
#
#
# ::
#
# PROTOBUF_IMPORT_DIRS - List of additional directories to be searched for
# imported .proto files. (New in CMake 2.8.8)
#
#
#
# Defines the following variables:
#
# ::
#
# PROTOBUF_FOUND - Found the Google Protocol Buffers library (libprotobuf & header files)
# PROTOBUF_INCLUDE_DIRS - Include directories for Google Protocol Buffers
# PROTOBUF_LIBRARIES - The protobuf libraries
#
# [New in CMake 2.8.5]
#
# ::
#
# PROTOBUF_PROTOC_LIBRARIES - The protoc libraries
# PROTOBUF_LITE_LIBRARIES - The protobuf-lite libraries
#
#
#
# The following cache variables are also available to set or use:
#
# ::
#
# PROTOBUF_LIBRARY - The protobuf library
# PROTOBUF_PROTOC_LIBRARY - The protoc library
# PROTOBUF_INCLUDE_DIR - The include directory for protocol buffers
# PROTOBUF_PROTOC_EXECUTABLE - The protoc compiler
#
# [New in CMake 2.8.5]
#
# ::
#
# PROTOBUF_LIBRARY_DEBUG - The protobuf library (debug)
# PROTOBUF_PROTOC_LIBRARY_DEBUG - The protoc library (debug)
# PROTOBUF_LITE_LIBRARY - The protobuf lite library
# PROTOBUF_LITE_LIBRARY_DEBUG - The protobuf lite library (debug)
#
#
#
# ::
#
# ====================================================================
# Example:
#
#
#
# ::
#
# find_package(Protobuf REQUIRED)
# include_directories(${PROTOBUF_INCLUDE_DIRS})
#
#

# ::
#
# include_directories(${CMAKE_CURRENT_BINARY_DIR})
# PROTOBUF_GENERATE_CPP(PROTO_SRCS PROTO_HDRS foo.proto)
# add_executable(bar bar.cc ${PROTO_SRCS} ${PROTO_HDRS})
# target_link_libraries(bar ${PROTOBUF_LIBRARIES})
#
#
#
# NOTE: You may need to link against pthreads, depending
#
# ::
#
# on the platform.
#
#
#
# NOTE: The PROTOBUF_GENERATE_CPP macro & add_executable() or
# add_library()
#
# ::
#
# calls only work properly within the same directory.
