Permission denied when trying to install packages with vcpkg classic

[maggiv8]

Hi there,

I am trying to compile a piece of source code on a Debian 12 system with Basic Gnome installation. To get started, I had to install ```
vcpkg following the steps below:
sudo apt install cmake blueprint-compiler git
git clone https://github.com/microsoft/vcpkg
cd vcpkg
./vcpkg/bootstrap-vcpkg.sh
export VCPKG_ROOT=/home/christoph/Downloads/vcpkg
export PATH=$VCPKG_ROOT:$PATH
export VCPKG_DEFAULT_TRIPLET=x64-linux
export CXX=/home/christoph/Downloads/vcpkg/downloads/tools/cmake-3.30.1-linux/cmake-3.30.1-linux-x86_64/bin/

Then I run the following command:
`vcpkg install boost-date-time gtest libnick libxmlpp`

At this step the issue arises. Here is the extract from 'config-x86-linux-rel-err.log':

Make Error at /home/christoph/Downloads/vcpkg/downloads/tools/cmake-3.30.1-linux/cmake-3.30.1-linux-x86_64/share/cmake-3.30/Modules/CMakeTestCXXCompiler.cmake:73 (message):
The C++ compiler

"/home/christoph/Downloads/vcpkg/downloads/tools/cmake-3.30.1-linux/cmake-3.30.1-linux-x86_64/bin/"

is not able to compile a simple test program.

It fails with the following output:

Change Dir: '/home/christoph/Downloads/vcpkg/buildtrees/detect_compiler/x64-linux-rel/CMakeFiles/CMakeScratch/TryCompile-zsdYP9'

However, even I execute `vcpkg install boost-date-time gtest libnick libxmlpp` as root via `sudo` I am getting the same error message. I also tried 'chmod 77 -R /home/christoph/Downloads/vcpkg/', but it didn't help.

Any idea how to fix this issue?
Thank you.
Best,
C,

export CXX=/home/christoph/Downloads/vcpkg/downloads/tools/cmake-3.30.1-linux/cmake-3.30.1-linux-x86_64/bin/
Why? This folder is your c++ compiler executable? This can't work.

Thank you. I changed it to point to the GCC executable by setting/exporting export CXX=/usr/bin/gcc. That solved this issue.
