Re: [CMake] FindBoost Warnings

[CMake] FindBoost Warnings
I am using FindBoost in a cmake script to determine if certain components of the boost package are available on the target system. If so, the script builds examples that use my package with boost. If not, these example are not built and tested. When the target system does not have boost, the user gets the warning: CMake Warning at /usr/share/cmake-3.10/Modules/FindBoost.cmake:567 (message): Imported targets and dependency information not available for Boost version (all versions older than 1.33) Call Stack (most recent call first): /usr/share/cmake-3.10/Modules/FindBoost.cmake:907 (_Boost_COMPONENT_DEPENDENCIES) /usr/share/cmake-3.10/Modules/FindBoost.cmake:1558 (_Boost_MISSING_DEPENDENCIES) CMakeLists.txt:245 (FIND_PACKAGE) This is not a problem because if the user's system does not have boost, they will no be using the case that the examples cover.

Re: [CMake] PROJECT( LANGUAGES ) and m4
Using a custom_command (not custom_target) and a looping over the output file names, I was able to get cmake to properly track the m4 output files and create them when necessary; see https://cmake.org/pipermail/cmake/2009-June/029909.html This seems to me like a good solution.

[CMake] detecting if c++11 available
My goal is to use some new c++11 features if they are available, otherwise to stick to the c++03 features. I need to build test programs that check for correctness as well as distribute an include file library. Is there a way in cmake to detect if c++11 is available and to use it when it is available ?

[CMake] ADD_CUSTOM_TARGET
I am trying to build a project for Red-hat 6 which uses the following cmake version bradbell@gorst trash]$ cmake --version cmake version 2.6-patch 4 While doing so I am having trouble with the ADD_CUSTOM_TARGET.

Below is an example CMakeLists for which make check works with cmake 2.8.9 and fails with 2.6-patch 4: CMAKE_MINIMUM_REQUIRED(VERSION 2.6) # PROJECT(hello) # ADD_EXECUTABLE(hello_one EXCLUDE_FROM_ALL hello_one.cpp ) ADD_EXECUTABLE(hello_two EXCLUDE_FROM_ALL hello_two.cpp ) # ADD_CUSTOM_TARGET(check_one hello_one DEPENDS hello_one) ADD_CUSTOM_TARGET(check_two hello_two DEPENDS hello_two) # ADD_CUSTOM_TARGET(check DEPENDS check_one check_two) I am attaching a bash script that creates the necessary files and runs the make check command.

Re: [CMake] Building a library for both C and C++
I have the same problem. The reason for the problem is that I am comparing the speed of the exact same source code compiled by C and C++. I have heard folk lore that C is faster, so I want an automated test to check for this for an arbitrary hardware and compiler. What I did was to create two source files, copied from the exact same original file, but with the .c and .cpp extensions using CONFIGURE_FILE.

Does that seem like a reasonable approach? Other suggestions welcome. Also, can anyone point me to an open source library that uses cmake and builds both a C and C++ version. I'd say this does not make any sense. The mylib++.a will still be a C library because all the compiled code in it will be C code unless your c files are somehow using a preprocessor macro to enable C and C++ code. And if they I'd say you'd be better off to split the files into a .c and a .cpp one and drop the macro. A C++ program can link to C libraries just fine, so there's really no need for that that I can see right now.

Is it possible to use a different name in place of CMakeLists.txt ?
