Debian，Cmake，Connot Compile C＆＃x2B;＆＃x2B;程序，缺少config cmake文件

Question

尝试编译 dot11decrypt 在Debian上和apt-get install libtins-dev，但是cmake ..找不到软件包libtins，Heres错误：

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!
See also "/home/user/dot11decrypt/build/CMakeFiles/CMakeOutput.log".

cat：dot11decrypt/

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)

cmakelists.txt -Name Findlibtins.cmake 或libtinsconfig.cmake不会带来任何结果。

我在互联网上找到了这些文件，但仍然没有成功，我认为我必须安装一些东西，但不知道什么。

Answer 1

我选择了Tsyvarev解决方案。

# 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

现在，cmake将到达dot11decrypt缺少文件。

# installing dot11decrypt
git clone https://github.com/mfontanini/dot11decrypt.git
cd dot11decrypt/
mkdir build
cd build/
cmake ../
make

现在，您应该具有DOT11DECRYPT可执行文件。

如果我必须再做一次，我将首先尝试Alex Reinking解决方案。

您无需从源头编译... find_package是一个非常灵活的配置点！您只需要提供自己的查找模块，而该模块足以构建。幸运的是，这很简单。这是我所做的：

$ 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.

这里的关键是创建一个最小的查找模块。这只是我系统上的两行，因为它不是可以重复使用的……

# _patches/Findlibtins.cmake
find_package(PkgConfig REQUIRED)
pkg_check_modules(LIBTINS REQUIRED libtins)

这只是将设置libtins_libraries设置为pkg-config的责任。要将此查找模块连接到构建，我只是设置-dcmake_module_path = $ pwd/_patches在cmake configure命令行。

另外，您应该肯定用dot11decrypt作者打开一个错误报告，内容涉及其破碎和过时的构建。请注意我发布的日志中措辞强烈的弃用警告。
