Cmake error: Could NOT find Boost (missing: Boost_INCLUDE_DIR)

问题

I am new to Cmake and Boost. I am now working on a program using cmake and need help.

System: windows 7
Cmake version: 3.16.0-rc1
Boost version: boost_1_71_0. And boost is installed through .exe file.
Gcc version: 4.8.1(rev5, Built by MinGW-W64 project)
Visual studio: vs 2015

When I run cmake .. in build dir, no error occurs. The output is:

The C compiler identification is MSVC 19.0.24215.1
The CXX compiler identification is MSVC 19.0.24215.1

But I want to use minGW to compile, so When I rum cmake -G "MinGW Makefiles", error occured saying "Could NOT find Boost (missing: Boost_INCLUDE_DIR)". The output is:

How to solve the error when running cmake -G "MinGW Makefiles"? Thanks guys!

回答1:

I solved this by adding sentence set(BOOST_ROOT C:/local/boost_1_71_0) before find_package(Boost REQUIRED) LOL... But I still wonder why I need to add this.

回答2:

You can also set variables BOOST_ROOT during the creation of the cmake project (or CMake options in CLion and other IDE). For example:

mkdir buildtest; cd buildtest
cmake -DBOOST_ROOT=/you_path_to_boost/boost ..
cmake --build . -- -j 4

回答3:

I had a similar problem on Linux/Manjaro. Make sure you have boost installed, more specifically the boost development headers. I had the boost runtime libraries installed but not the headers. I installed those sudo pacman -S boost and it fixed the problem for me.

回答4:

After I solved this problem, thanks to ToughMind here, these problems occurred to me: _Boost_COMPONENT_DEPENDENCIES and _Boost_MISSING_DEPENDENCIES. What helped me was to update to the newest cmake verison and I got the answer from here: CMake finds Boost but the imported targets not available for Boost version
