-### Modifying build settings in the Visual Studio IDE
+##### Static Builds
+
+The default (and recommended) builds of Exiv2 and sample applications build and use DLLs.  If you wish to build static applications and libraries, you will need to set the correct "C" run-time library to be linked both to your code and dependencies being built/downloaded by conan.
 
-**CAUTION** You can change the runtime library in Visual Studio once you open the
-solution generated by CMake.  If you have generated a project to use the dynamic run-time library
-with the profile setting `compiler.runtime=MD` (or MDd), Visual Studio allows you to change that setting.
-However the libraries (provided by conan) to which you link are tied
-to a specific configuration and you will obtain linking errors.
+| Static Release | Static Debug |
+|:---------|:-------------------|
+| compiler.runtime=MT | compiler.runtime=MTd |
 
-If you want to work with the static runtime library `MT` (or `MTd`), set up the profiles and build in a different directory such as build-static.
+Additionally, you will have to use the cmake option -DBUILD\_SHARED\_LIBS=Off to
+
+```
+$ cmake -DBUILD_SHARED_LIBS=Off ..

 ### Changing profile settings with the conan command
 
 It is recommended that you create 8 profiles for msvc{2017|2015}{Release|Debug}{64|32}.
 
 You can modify profile settings on the command line.
