Re: [CMake] configure_file as a build step?
You can configure_file() a CMake-script which itself then performs the
configure_file() in a custom command. E.g.:
# CMakeLists.txt:
#...
set(FOO "Some text to show up in json_file.json")
set(BAR "More text")
configure_file(configure_json_file.cmake.in
${CMAKE_CURRENT_BINARY_DIR}/configure_json_file.cmake @ONLY)
add_custom_command(OUTPUT ${CMAKE_CURRENT_BINARY_DIR}/json_file.json
COMMAND ${CMAKE_COMMAND} -P
${CMAKE_CURRENT_BINARY_DIR}/configure_json_file.cmake
DEPENDS
${CMAKE_CURRENT_BINARY_DIR}/configure_json_file.cmake
${CMAKE_CURRENT_SOURCE_DIR}/json_file.json.in
COMMENT "Configuring json_file.json"
VERBATIM)
add_custom_target(configure_json ALL
DEPENDS ${CMAKE_CURRENT_BINARY_DIR}/json_file.json)
#...
# EOF
# configure_json_file.cmake.in:
set(SRC_DIR "@CMAKE_CURRENT_SOURCE_DIR@")
set(BIN_DIR "@CMAKE_CURRENT_BINARY_DIR@")
set(FOO "@FOO@")
set(BAR "@BAR@")
configure_file(${SRC_DIR}/json_file.json.in
${BIN_DIR}/json_file.json @ONLY)
# EOF

[CMake] configure_file as a build step?
I have a JSON file that needs to have some values set based on the project's configuration. During development, this file can change rather frequently. Currently, I am using configure_file to fill in the required values. Unfortunately, every time the file is modified, it triggers CMake to do a complete configuration and generation step. This slows down rebuilds, and is especially problematic when using Visual Studio, where the solution has to be reloaded after it is regenerated. Is there any way to have the file generated as part of the build instead of part of the configuration/generation step?

Re: [CMake] CMake 2.8.8 bug with cmake-gui and stop button
It's a bug. You should not be able to generate unless a configure step has *completed* successfully. A good demonstration of the fact that GUI changes are hard to test.

[CMake] CMake 2.8.8 bug with cmake-gui and stop button
Remember that change that was made to make pressing stop in cmake-gui more responsive? I'm finding an issue now where during configure, if I stop, it stops without failing, which allows me to press generate on a partial configuration. I'm not sure if this is a bug of feature but I thought I'd mention it. I output text in my CMake scripts for each target I create and configure: Checking for new third party libraries (might take a few minutes)... _copy_dlls being generated (may take a while) BUILD_VERSION is: 6.3.2.14 + testharness --> common/testharness/CMakeLists.txt + gdutil --> common/util/CMakeLists.txt Configuring done Generating done I pressed stop and nothing failed after configuring 'gdutil' target. I have at least 100 other targets that are supposed to generate after that.

Re: [CMake] [Boost-users] link error in Visual Studio when using boost from CMake
Yes, target_link_libraries works well, I had problem before because I used
find_package(Boost) instead of find_package(Boost COMPONENTS thread), so
when I used target_link_libraries( MyProject ${Boost_LIBRARIES} ), it
didn't link anything, after I specify the components in find_package, it
has no problem.

Nope. I don't use link_directories at all and I use Boost on windows all the
time. I use the "target_link_libraries(...) method and it has NEVER give me any
trouble on windows with VS 2005, 2008 and 2010.
YMMV (but it shouldn't)

Unless you disable Boost auto-linking, i'm afraid it's the only option.
Boost autolinking is enabled by default for Visual Studio. In this case,
Boost headers have pragmas to link to Boost libs.
#pragma comment (lib, "libboost_.lib")
If you don't add Boost_LIBRARY_DIRS to the link directories, it won't
work.

No, please don't. The target_link_libraries command is what you really want.
Please stop advertising link_directories, it's usage is almost certainly wrong
and while it sometimes seems to solve your problem it usually just creates
another one.
