using vcpkg to download dependencies without create dll
When using vcpkg
to download dependencies for your C++ project, you have the option to build the dependencies statically instead of dynamically (DLL). This can help you avoid creating DLLs and instead link the dependencies statically into your final executable. Here's how you can do it:
Install Dependencies with vcpkg:
First, you need to install your project's dependencies usingvcpkg
. Open a command prompt or terminal and navigate to yourvcpkg
directory. Then, run the following command to install your desired packages:bashvcpkg install package1 package2 package3
Replace
package1
,package2
, etc., with the names of the packages you want to install.Specify
vcpkg
Toolchain File:
When building your project, you need to specify thevcpkg
toolchain file to ensure that the correct dependencies and settings are used. Set theCMAKE_TOOLCHAIN_FILE
variable to the path of thevcpkg
toolchain file:bash-DCMAKE_TOOLCHAIN_FILE=C:\path\to\vcpkg\scripts\buildsystems\vcpkg.cmake
Configure and Build Your Project:
Now, configure and build your C++ project using CMake and thevcpkg
toolchain file. For static linking, you can use the following CMake configuration:bashmkdir build
cd build
cmake .. -DCMAKE_TOOLCHAIN_FILE=C:\path\to\vcpkg\scripts\buildsystems\vcpkg.cmake -DBUILD_SHARED_LIBS=OFF
cmake --build .
In this example,
BUILD_SHARED_LIBS=OFF
specifies that you want to build statically linked libraries.
By configuring your project to build with static dependencies, you'll include the necessary code from the dependencies directly into your executable, without the need for separate DLL files. This can simplify distribution and deployment, but keep in mind that static linking can result in larger executable files.
Be aware that some dependencies might require additional steps to properly configure static linking. Always refer to the documentation for both your dependencies and vcpkg
for the most accurate instructions.
