CMake reports 'Boost_DIR-NOT_FOUND' when trying to find Boost
boost, cmake
Solution
It seems you misunderstood the meaning of `Boost_DIR`.
`Boost_DIR` is an environment variable used as a hint by CMake to find the boost installation directory. If this is set to `Boost_DIR-NOTFOUND` that does not mean that it did not find Boost. `Boost_FOUND` is used to indicate whether the search was successful:
find_package(Boost REQUIRED thread)
if(Boost_FOUND)
message(STATUS "Success!")
endif()
In case of a successful search, CMake will also print a diagnostic message during the configure phase which looks something like
Boost version: 1.53.0

Problem
I want to build a library called CSWNet on my machine. Cmake can find Boost_INCLUDE_DIR and Boost_LIB_DIR but it cannot find an option called Boost_DIR which is a directory containing a CMake configuration file for Boost. Where is it? Please help, thanks ahead. The error I got is shown below and I installed boost from ubuntu repository and it's installed in /usr/local. ``` CMake Error at /usr/local/share/cmake-2.8/Modules/FindBoost.cmake:429 (message): When requesting a specific version of Boost, you must provide at least the major and minor version numbers, e.g., 1.34 Call Stack (most recent call first): demos/CMakeLists.txt:149 (find_package) ```
