Details

Description:

CMake integration of find_package(Boost) incorrectly resolves the Boost_INCLUDE_DIRS to "/include", resulting in the build failure of projects that have boost as a dependency


Additional info:

Version 1.71.0-2 has the issue, 1.69.0-2 was fine

Steps to reproduce:

(Minimal CMakeLists.txt)

```
project(boostTest)
find_package(Boost REQUIRED)
message(STATUS "-> ${Boost_INCLUDE_DIRS}")
```

running `cmake .` will show that Boost_INCLUDE_DIRS is resolved to "/include" instead of "/usr/include"
This task depends upon

Odd... I get

```
-- Found Boost: /lib64/cmake/Boost-1.71.0/BoostConfig.cmake (found version "1.71.0")
-- -> /include
```

But if I rollback (or install boost1.69)

```
-- Found Boost: /usr/include (found version "1.69.0")
-- -> /usr/include
```

What's the full cmake output with -DBoost_DEBUG=ON ?

What is your $PATH?
Comment by Rodrigo Fernandes (rfernandes) - Tuesday, 15 October 2019, 12:00 GMT
PATH=/bin:/usr/bin:/usr/local/bin:/usr/local/sbin:/usr/lib/jvm/default/bin:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl

"PATH=/bin" there's your problem. Remove this from your PATH.

You may want to suggest upstream to change ABSOLUTE to REALPATH in boost_headers-config.cmake, this will make it work even with /bin in PATH.
