[CMake] Boost library directory not found unless I explicitly set BOOST_LIBRARYDIR ?

[Glenn Coombs]

Hi,

I have installed Boost on Windows 7 for Visual Studio 2013 by running these
installers:

boost_1_56_0-msvc-12.0-32.exe
boost_1_56_0-msvc-12.0-64.exe

downloaded from
http://sourceforge.net/projects/boost/files/boost-binaries/1.56.0/.

I'm using CMake 2.8.12.1 and when I try to build a simple Boost example
using the filesystem library my cmake configuration step fails to find the
required libraries unless I use the BOOST_LIBRARYDIR variable to tell it
where the libraries are:

set(BOOST_VERSION_NEEDED 1.53.0)

if (MSVC)
    set(Boost_USE_STATIC_LIBS       ON)
    set(Boost_USE_MULTITHREADED     ON)
    set(Boost_USE_STATIC_RUNTIME    ON)
#   set(BOOST_LIBRARYDIR            /Boost/boost_1_56_0/lib64-msvc-12.0)
endif()

find_package(Boost ${BOOST_VERSION_NEEDED} REQUIRED COMPONENTS system
filesystem)

Given that the library directory is where the official Boost installer put
it shouldn't the FindBoost.cmake package be checking that directory by
default ?

This is the output from CMake:

Could NOT find Boost

Boost version: 1.56.0

Boost include path: C:/Boost/boost_1_56_0

Could not find the following static Boost libraries:

boost_system

boost_filesystem

No Boost libraries were found. You may need to set BOOST_LIBRARYDIR to the
directory containing Boost libraries or BOOST_ROOT to the location of Boost.


As you can see it is looking for a directory called lib rather than
lib64-msvc-12.0.
