See the documentation for your software for details on the exact process for generating the normal map.

The geometry of the high-res detail mesh is used to generate the normals for the normal map. Normal maps can be created for your meshes directly inside of most modeling applications by creating both a low-res render mesh and a high-res detail mesh. Complete details on setting up UVs for static meshes are detailed on the Unwrapping UVs for Lightmaps page. However, there are some general considerations for setting up UVs with static meshes that need to be accounted for. There are no special requirements for setting up the UVs for static meshes using the FBX pipeline. For static meshes, this is generally used to handle one set of UVs for the diffuse and another separate, non-overlapping set of UVs for use with lightmaps. The import of multiple UV sets is supported by the FBX pipeline in Unreal Engine 3. Automatic triangulation can lead to undesirable results. It will always be best to manually triangulate the mesh in the 3D application, controlling the direction and placement of edges. Allow the importer to triangulate the mesh - okay solution, allows no cleanup but can work for simple meshes.Allow the FBX exporter to triangulate the mesh - okay solution, allows no cleanup but can work for simple meshes.Triangulate the mesh in the 3D app - good solution, allows cleanup and modification before export.Model the mesh with only tris - best solution, provides the most control over the end result.There are several ways you can ensure your mesh is triangulated. Meshes in Unreal Engine must be triangulated as the graphics hardware only deals with triangles. Because of this, it is best to create your meshes at the origin, with the origin generally being located at one corner of the mesh to allow for proper alignment when snapping to the grid inside of Unreal Editor. The pivot point is always located at the origin (0,0,0) when exporting from a 3D modeling application. The pivot point of the mesh in Unreal Engine determines the point around which any transformations (translation, rotation, scale) will be performed. Importing into UnrealEd will fail if the mesh has more than 65535 vertices. Note: Static meshes are limited to 65535 vertices. that you need to account for in order for the exporting and importing to go smoothly and for the mesh to work properly in Unreal Editor. There are some stipulations as far as setting up UVs, placement of the mesh, etc.

In general, you are free to create static meshes using any tools and methods you want.
