Unable to build from source using README.md instructions

[scudette]

This might be a noob question but I am unable to build from source using the instructions. I am not very familiar with cmake or vcpkg so maybe this is the issue (it has been a while since i fought with c++).

I installed vcpkg from source and built it fine, then it seems to install pe-parse correctly, but when trying to build uthenticode it cant find it and i cant figure out how to tell it where it is installed.

mic@devbox:~/projects/uthenticode$ ~/projects/vcpkg/vcpkg install pe-parse
Computing installation plan...
The following packages are already installed:
    pe-parse[core]:x64-linux -> 1.2.0
Package pe-parse:x64-linux is already installed

Total elapsed time: 47.66 us

The package pe-parse:x64-linux provides CMake targets:

    find_package(pe-parse CONFIG REQUIRED)
    target_link_libraries(main PRIVATE pe-parse::pe-parser-library)

mic@devbox:~/projects/uthenticode$ mkdir build && cd build
mic@devbox:~/projects/uthenticode/build$ cmake ..

CMake Error at src/CMakeLists.txt:5 (find_package):
  By not providing "Findpe-parse.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "pe-parse",

  Could not find a package configuration file provided by "pe-parse" with any
  of the following names:

    pe-parseConfig.cmake

  Add the installation prefix of "pe-parse" to CMAKE_PREFIX_PATH or set
  "pe-parse_DIR" to a directory containing one of the above files.  If
  "pe-parse" provides a separate development package or SDK, be sure it has
  been installed.

Sorry for this - i figured it out. I first needed to install vcpkg properly:

mic@devbox:~/projects/uthenticode/build$ ~/projects/vcpkg/vcpkg integrate install
Applied user-wide integration for this vcpkg root.

CMake projects should use: "-DCMAKE_TOOLCHAIN_FILE=/home/mic/projects/vcpkg/scripts/buildsystems/vcpkg.cmake"
mic@devbox:~/projects/uthenticode/build$ cmake -DCMAKE_TOOLCHAIN_FILE=/home/mic/projects/vcpkg/scripts/buildsystems/vcpkg.cmake ..

From a clean build directory worked to properly configure the project and it built then.

Thanks for posting your solution! Yep, you need to configure CMake to get its packages from the vcpkg toolchain. It's a little annoying, but you should only need to do it once per CMake build (or set it globally in your environment).

I'd be happy to accept a PR that tweaks the README slightly to include a reference to CMAKE_TOOLCHAIN_FILE 😄
