Privilege check
===============

[![AppVeyor branch](https://img.shields.io/appveyor/ci/egor-tensin/privilege-check/master?label=AppVeyor)](https://ci.appveyor.com/project/egor-tensin/privilege-check/branch/master)

Check your privilege. On Windows.

Displays a window, showing

* if the current user belongs to the BUILTIN\Administrators group,
* whether the process is "run as Administrator",
* if it has elevated privileges,
* process's "integrity level".

If it's not "run as Administrator", a button allows to actually re-run the
executable as Administrator, utilizing Windows' User Account Control feature.

Building
--------

Create the build files using CMake and build using your native build tools
(Visual Studio/make/etc.).

* **Example (Visual Studio).**
In the example below, the project directory is
"C:\workspace\personal\privilege-check" and Visual Studio 2015 is used,
targeting x86-64.

      > cmake -G "Visual Studio 14 2015 Win64" C:\workspace\personal\privilege-check
      ...

      > cmake --build . --config release
      ...

* **Example (MinGW-w64).**
Another example, this time using Cygwin + MinGW-w64, targeting x86-64
(the project directory is "/cygdrive/c/workspace/personal/privilege-check").

      > cmake -G "Unix Makefiles"                         \
          -D CMAKE_CXX_COMPILER=x86_64-w64-mingw32-g++    \
          -D CMAKE_RC_COMPILER=x86_64-w64-mingw32-windres \
          -D CMAKE_BUILD_TYPE=Release                     \
          /cygdrive/c/workspace/personal/privilege-test
      ...

      > cmake --build . -- -j
      ...
