Debian, cmake, connot compile c++ program, missing config cmake file - c++

Question

Trying to compile dot11decrypt on debian, installed apt-get install libtins4.0 and apt-get install libtins-dev, but cmake .. can't find package libtins, heres the error:
CMake Error at CMakeLists.txt:4 (FIND_PACKAGE):
By not providing "Findlibtins.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "libtins", but
CMake did not find one.
Could not find a package configuration file provided by "libtins" with any
of the following names:
libtinsConfig.cmake
libtins-config.cmake
Add the installation prefix of "libtins" to CMAKE_PREFIX_PATH or set
"libtins_DIR" to a directory containing one of the above files. If
"libtins" provides a separate development package or SDK, be sure it has
been installed.
-- Configuring incomplete, errors occurred!

cat:dot11decrypt/CMakeLists.txt
1. CMAKE_MINIMUM_REQUIRED(VERSION 2.8.1)
2. PROJECT(dot11decrypt)
3.
4. FIND_PACKAGE(libtins REQUIRED)
5.
6. SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++0x")
7.
8. ADD_EXECUTABLE(dot11decrypt dot11decrypt.cpp)
9. TARGET_LINK_LIBRARIES(dot11decrypt ${LIBTINS_LIBRARIES} pthread)
find / -name Findlibtins.cmake or libtinsConfig.cmake brings no result.
I found those files on internet but still no success, i think i have to install something but don't know what.

Answer 1

I went with Tsyvarev solution.
# installing missing dependencies for libtins
apt-get install libpcap-dev libssl-dev cmake
# installing libtins
git clone https://github.com/mfontanini/libtins.git
cd libtins
mkdir build
cd build
cmake ../
make
checkinstall
Now cmake will reach dot11decrypt missing files.
# installing dot11decrypt
git clone https://github.com/mfontanini/dot11decrypt.git
cd dot11decrypt/
mkdir build
cd build/
cmake ../
make
Now you should have dot11decrypt executable.
If i would have to do it again i would try Alex Reinking solution first.

You don't need to compile from source... find_package is a very flexible configuration point! You'll just need to provide your own find module that is sufficient for the build. Fortunately, this is very simple. Here's what I did:
$ https://github.com/mfontanini/dot11decrypt
$ cd dot11decrypt
$ mkdir _patches
$ vim _patches/Findlibtins.cmake
$ cat _patches/Findlibtins.cmake
find_package(PkgConfig REQUIRED)
pkg_check_modules(LIBTINS REQUIRED libtins)
$ cmake -S . -B build -DCMAKE_BUILD_TYPE=Release -DCMAKE_MODULE_PATH=$PWD/_patches
CMake Deprecation Warning at CMakeLists.txt:1 (CMAKE_MINIMUM_REQUIRED):
Compatibility with CMake < 2.8.12 will be removed from a future version of
CMake.
Update the VERSION argument <min> value or use a ...<max> suffix to tell
CMake that the project does not need compatibility with older versions.

The key here is to create a minimal Find module. This is just two lines on my system since it isn't meant to be reusable...
# _patches/Findlibtins.cmake
find_package(PkgConfig REQUIRED)
pkg_check_modules(LIBTINS REQUIRED libtins)
This just delegates the responsibility of setting the LIBTINS_LIBRARIES to pkg-config. To connect this find module to the build, I just set -DCMAKE_MODULE_PATH=$PWD/_patches at the CMake configure command line.
Also, you should definitely open a bug report with the dot11decrypt author about their broken and outdated build. Notice the strongly worded deprecation warning in the logs I posted.
