Build issues in hide-formfields

[fless-lab]

The current CMakeLists.txt configuration for the hide-formfields module has issues when trying to locate and link with Qt5 and Poppler libraries. These issues prevent successful compilation on certain systems, leading to build errors.

Problem:

• The CMakeLists.txt file does not reliably find and link Qt5 and Poppler libraries, resulting in build failures.
• This affects users who try to build hide-formfields on systems where the paths to these dependencies may vary.

Proposed Solution:

• Update CMakeLists.txt to use find_package for Qt5, ensuring that the necessary libraries and include directories are correctly detected.
• Correct the include directories and library linking configurations for Poppler.

Steps to Reproduce:

1. Clone the repository.
2. Navigate to the cpp/hide-formfields directory.
3. Run the build command (e.g., ./build.sh).

Expected Behavior:

The hide-formfields module should compile successfully without errors.

Actual Behavior:

The build fails due to missing or incorrectly linked Qt5 and Poppler dependencies.
